View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.ALLEGHENY A-286 is an austenitic iron-nickel-chromium alloy designed for service up to 1300 F where high strength and corrosion resistance are required, and for service at higher temperatures where the applications are for lower stresses. It is an age-hardenable alloy.
